Echeveria and weather

strelitzia32

The weather is going a bit strange here. It was 1 degree last night with ground frost, and now it's 15 degrees and sunny outside, almost 18 in my greenhouse. 

My echeveria is in the greenhouse, and usually I keep them dry over winter. Except with these daytime temperatures I think I need to water more, but I'm concerned about rotting etc when the temperature drops so significantly at night.

Any thoughts on what to do for the best? What is everyone else doing? They are large elegans, regular flowering, so I'd rather not lose them!

I have had them totally dry in a greenhouse over winter.  Better too dry than too wet.

I keep them in the unheated greenhouse, but water very sparingly, every few weeks.  It can get quite warm in our greenhouse over Winter, and I found that zero watering resulted in them starting to die off.  This is such a slow process that you can usually spot it, and rectify with a tiny bit of watering.  If your greenhouse is consistently cold and shaded over Winter, then the zero watering approach is probably better.

Thanks both, I'll keep an eye on them and won't up the watering.

15 degrees in November. Madness.
